First published in 1834 as The Round Towers of Ireland or the Mysteries of Freemasonry, of Sabaism, and of Budhism, this book was an instant sensation as one of the first modern studies of Atlantis, round towers, pre-Christian megalithic architecture and secret societies. In addition to being a sourcebook on Atlantis Research, Druidic Culture and origins of modern Celtic Christianity, the book is a treasurehouse of ancient esoteric lore and arcane knowledge of the past, including: The History of the Tuath-de-Danaans, The Round Towers and Megalithic Crosses of Ireland are pre-Christian, Ireland's strange connections with ancient India, Persia and China, Ancient Secret Societies and Ireland, Ancient Egyptians and Ireland, Pre-Christian Messiahs, Mithraism, and Ireland, The Connections Between Atlantis and Ireland
